OBD-II Diagnostic Trouble Code
P1410 — EVAP System Pressure Sensor
P1410 is a manufacturer-specific code, mainly on gasoline trucks, that with this title commonly means a fault in the EVAP system pressure sensor or its circuit. The ECM saw a sensor reading that is out of range or not plausible. Meaning can vary by OEM.

What this means for truckers
P1410 (EVAP System Pressure Sensor) — gas engine code, EVAP issue.
Before you replace parts — try this first
P1410 on the Emissions system is most often faulty evap pressure sensor — not a dead part. On commercial diesels especially, work these in order before spending money on parts:
- Confirm the symptoms. Match what your truck is doing to the Symptoms section below. If the code is set but the symptoms are not there, clear the code and re-test after a drive cycle — it may not return.
- Clean and dry the sensor connector. Water, road salt, or oil seeping into a connector is the #1 fake sensor failure. Disconnect, look for green corrosion or moisture, spray with electrical contact cleaner, dry, reseat. Many faults clear here for $0.
- Inspect the wiring harness. Trace the wire from the sensor toward the ECM — look for chafing against the engine block, melted insulation near the turbo or exhaust, or pinch points where a clamp has rubbed through.
- Test the sensor before swapping it. Most Common Causes (below) list the expected voltage or resistance range — a $20 multimeter saves a $300 sensor swap that does not fix the problem.
- Only then, replace the part. Use the OEM or a tier-1 aftermarket. Cheap sensors throw the same code in two weeks.
Symptoms
Usually only a check-engine light with no drivability change. Other EVAP codes may also set and the truck may fail an emissions inspection.
Common causes
- CommonFaulty EVAP pressure sensor ($100–$350)
- CommonWiring or connector fault ($80–$300)
- OccasionalShared 5V reference circuit problem ($100–$400)
- RareECM fault ($500–$1800)
How to fix
Check the sensor reading with the fuel cap off, where it should show atmospheric pressure
When to use: First step
Check the sensor 5V reference, ground and signal wiring and connector
When to use: When readings are erratic or stuck
Replace the EVAP pressure sensor
When to use: When the sensor is out of spec with good wiring

Frequently Asked Questions
Can I drive with code P1410?
P1410 is severity 2 — service this week. Not an immediate stop, but ignoring it usually compounds the problem. Most common cause for this code is a worn sensor or minor performance fault that won't strand you today but will get more expensive the longer you wait.
How much does it cost to fix P1410 on a commercial truck?
Total repair cost ranges $80–$1800 depending on the root cause. The cheapest fix is usually the first one listed below — Faulty EVAP pressure sensor — which is also the most common. On commercial trucks the cost is usually higher than passenger vehicles due to part availability and shop labor rates ($120–185/hour at most truck shops, vs $90–130 at general auto shops). DIY-capable fixes (sensors, hoses, filters) are at the low end; major component replacements (turbo actuator, high-pressure fuel pump, transmission solenoid pack) are at the high end. Always diagnose with a scan tool BEFORE replacing parts — guessing wrong on a $1,500 turbo actuator when the actual issue was a $30 boost hose is a common expensive mistake.
Will P1410 fail a DOT inspection?
Yes — P1410 is an emissions-related code, and DOT inspectors check emissions compliance. An active emissions code with a check engine light can result in an out-of-service violation under FMCSA Part 393. The truck typically can't be moved until the code is cleared. Repeated emissions violations escalate to CSA scores.
What's the difference between P1410 and related codes?
P1410 is closely related to: P1404 (EGR Closed Position Performance), P1450 (Unable to Bleed Up Fuel Pressure), P1455 (EVAP System Leak (Gross Leak)). These codes share the same subsystem (emissions) and often appear together. If you see this code, scan for the full code list — fixing the root cause usually clears multiple companion codes at once. If only P1410 is set without the companions, the issue is more isolated.
How do I prevent P1410 from coming back after a repair?
For P1410 (EVAP System Pressure Sensor), prevention centers on the emissions system. Keep up with PM on the EGR system — clean the valve at 200K miles. Use OEM-spec air filters. Don't ignore minor codes; they often escalate into bigger emissions failures.
